5 Claims.

'Ihis invention relates to certain new and useful'l improvements in thebobbin or yarn package holders used in the spinning art.

It has for one off its objects to provide a holder. of this characterwhich has been designed the thread' is taken off' the bobbin and therebyeliminate snarling, knotting or breaking of the threads.

Other features of the invention reside in the construction andarrangement of parts hereinafter described. and particularly pointed outin the appended claims.

In the accompanying drawing:

Figure 1 is a fragmentary front View of a portion of a spinning machineshowing my improved b-obbin holder structure associated therewith.Figure 2 is an enlarged central longitudinal section of the bobbinholder and associated parts. Figure 3 is a top plan View of the bobbinholder. Figure 4 is an enlarged vertical section taken on line 4 4,Figure 2. Figure 5 is an exploded perspective view of the bobbin holderelements.

Similar characters of reference indicate corresponding parts throughoutthe several views.

Referring now to the drawing, Ill indicates the bobbin-spindle, II thetake-off bobbin mounted thereon, I2 the flyer-body on which the flyerwires I3 are mounted for guiding the threads from the lbobbin to a guideor centering eye I4, from which the threads lead to a takeup spool (notshown). The flyer shown is of the eccentric type and the core or barrelI5 of the bobbin holder has a recess I6 in its top having an invertedcup-like opening I'I therein arranged concentric to the axis of thebobbinspindle.

'I'he package of silk-rayon or like material to be spun is an open-endedone and consists of a sleeve I8 having the material I9 wound thereon ina manner to provide substantially conical or beveled ends 20 radiatingfrom the companion ends of the sleeve, as shown in Figure 2. Theseconical ends of the package may be deflected either inwardly oroutwardly. The bore of the package-sleeve is somewhat larger in diameterthan that of the barrel I5 so as to be readily applied thereto andremoved therefrom.

Secured to the lower end of the barrel I5 by screws or like fasteningsis a head-plate 2i which is of a diameter toV extend somewhat beyond theedges of the package I8, I9 and which is preferably'dished or ofinverted conical shape, as shown in Figures 24 and 5. Extending aboutthe lower end of the barrel and rising axially from this plate is acollar or `ferrule 22 which extends into the package-sleeve I8 tofrictionally hold the package on the barrel. After the package isapplied to the barrel, a plate 23 may be placed over its top to keep thepackage clean, such plate having a collar 24 thereon which frictionallybinds it between the barrel and the sleeve I8.

Disposed over the top side of the head-plate 2l for yieldablebearingengagement with the opposing end of the package I9 isa resilientdiaphragml or' ring-like plate 25 of thin metal which is retained at itsperiphery to the marginal edge or in an inwardly-facing annular grooveformed in the head-plate by a hanged band or collar 25, while its innerportion is freefloating. Normally this diaphragm spans the dishedhead-plate in a horizontal plane so that suii'icient space is providedfor the yieldable displacement of the diaphragm toward the plate, in themanner shown in Figure 2. When the package is applied to the barrel, thelower end of the package abuts the yieldable diaphragm 25 and aords aneffective seal or joint at the lower outer edge of the package forpreventing the threads from the package working under the bottom thereofduring the spinning operation. As the thread is payed off the package,the resilient diaphragm follows in close contact with the conical bottomof the package and always forms a closed joint at the peripheral edgethereof. While the periphery of the diaphragm is retained by the flangedband 26, the connection is such that the diaphragm is comparatively freefor the full displacement required. About its center opening thisdiaphragm has a flange 21 which bears against the paper sleeve I8 of thethread package so as to allow all of the thread to be unwound therefromduring the twisting operation.

To prevent the thread from running over the upper end of the package,the take-off flyer wire I3 with the depending eye is so disposed thatsuch eye is always located below the upper end of Vthe package.

By preference, the flyer body I2 is provided with a suitable brakeelement 28 which may be thereof, said head-plate havingan inwardly-fac--ing annular groove at its outer edge and being substantially of conicalshape, and a flat resilient metallic diaphragm-like member freelysupported at its periphery in said plate groove for bearing engagementwith the opposing end of the package.

2. A bobbin or yarn package holder, comprising a barrel having ahead-plate fixed at one end thereof, said head-plate being substantiallyof conical shape and having a retaining band at its periphery forming aninwardly-facing annular groove, and a normally flat resilientdiaphragm-like member of thin metal disposed over said head-plate foriioating movement relative thereto and in loose-fitting engagement atits periphery with said retaining band groove.

3. A bobbin or yarn package holder, comprising a barrel having ahead-plate at one end thereof, a resilient diaphragm-like membersuperposed on said plate for displacement axially of the barrel intoyieldable bearing engagement with the opposing end of the thread-portionof the package, said `diaphragm member having va flanged inner portionabout the axis thereof for bearing engagement with the core portion ofthe package, and means applied to the head-plate including a collarhaving an inwardly-facing groove for anchoring said diaphragm member atits periphery to said head-plate, said means per'- mitting a freedisplacement of the diaphragm at all times.

4. The combination with a bobbin-spindle and an open-ended package ofmaterial to be spun, of a package-receiving barrel adapted forattachment to said spindle and having a head-plate at its lower end ofinverted conical shape, a retaining band at the periphery of thehead-plate and having an inwardly-facingY annular` groove therein, acollar extending about the lower end of said barrel for frictionallyretaining the package thereon, and a resilient diaphragm of thin metalsuperposed on said head-plate and loosely tted -at its periphery in thegroove of said retaining band, the remaining portion of the diaphragmspanning the opposing face of the headplate in spaced relation theretofor displacement axially toward the same and adapted for sealing bearingengagement with the lower end of the package.

5.- A yarn package holder of the character de.- scribed, comprising apackage-receiving barrel adapted for attachment to the bobbin-spindle, ahead-plate secured to the bottom of the barrel about the spindle andprojecting upwardly and outwardly therefrom in substantially invertedconical fashion and against which the lower end of the package-sleeve isadapted to abut, the periphery of said plate having an inwardly-angedretaining band applied thereto forming an annular groove, and aresilient ringlike plate of thin metal superposed on said headplate andhaving its marginal edge loosely seated in said retaining band grooveand its body portion spanning the opposing face of the headplate inspaced relation thereto for displacement toward the same and adapted forsealing bearing engagement with the lower end of the package about itssleeve.
